Filtering Google Search Results Using Top-Level Domains
A book chapter: Simply by entering keywords into the primary Google search box, researchers usually find useful information. But even better results are obtained by applying filtering techniques. Top-level domains (TLDs) are an effective tool to sort information retrieved from the Internet and get highly relevant results. In scientific research on topics related to forestry, for example, filtering by the dot gov TLD, a user immediately finds publications from government departments and agencies, eliminating the need to drill down through dozens of pages which can be filled with less valuable and often general information.
